Problems solved by technology

Because of the particularity of the backlight structure, as long as there are defects in some film materials, or foreign matter in the middle and other defects exceeding the standard, the backlight product will be completely scrapped.
[0003] At present, the entire backlight manufacturing industry has no direct rework plan for film materials. The current repair method is mainly manual repair. This process can easily cause deformation of the plastic frame, wrinkles of the film material, scratches on the light guide plate, and foreign objects in the reflective film. , resulting in a very low repair yield rate, and basically the film materials that can be reworked cannot be reused

Abstract

The invention discloses a method for increasing the reworking recycling utilizing rate of backlight products. The method includes the following steps that the to-be-reworked backlight products are cleaned; the light shielding glue positions on the surfaces of the backlight products are avoided and the backlight products are covered and pressed; light shielding glue is removed and covering and pressing are removed; and various layers of backlight film materials in the backlight products are sequentially sucked and recycled from top to bottom. According to the method, the backlight products arecleaned in the reworking early stage, and a high cleanness degree of the surfaces of the backlight products is guaranteed; then the light shielding glue positions of the surfaces of the backlight products are avoided and the backlight products are covered and pressed; it is prevented that when the light shielding glue is removed, the backlight film materials are taken up; deformation wrinkles of the backlight film materials and plastic frame or iron frame deformation are avoided, the various layers of backlight film materials are recycled in sequence, the reworking yield is increased, and themanual reworking cost and the raw material cost are saved.

Description

technical field [0001] The invention relates to the field of backlight product manufacturing, in particular to a method for improving the rework and recycling rate of backlight products. Background technique [0002] The pursuit of zero loss of each component material of the finished product is one of the main research directions in the existing manufacturing industry. Because of the particularity of the backlight structure, as long as there are defects in some film materials, or foreign matter in the middle and other defects exceeding the standard, the backlight product will be completely scrapped. [0003] At present, the entire backlight manufacturing industry has no direct rework plan for film materials. The current repair method is mainly manual repair. This process can easily cause deformation of the plastic frame, wrinkles of the film material, scratches on the light guide plate, and foreign objects in the reflective film. , resulting in a very low repair yield rate,...
